just tried to tile on to existing painted tounge and groove in kitchen managed to get 36 tiles up after it started to dry they all fell back off are the tiles im using to big or do i need a different adhesive please advise desperate.
Tiling onto timber is a bad idea Darren as a) it dries the adghesive out so quickly because it is so porous, and b) Timber moves, expanding and contraction all the timke especially in humid places like kitchens and bathrooms. You can have another go by painting the timber with two, undiluted coats of PVA adhesive ( See our project on PVA Adhesive) and then tiling. The PVA gives a waterproof skin on the timber and allows the adhesive to stick properly.
